CORNELIUS A. DIE-SIMONE, OF VENTNGR, NEW JERSEY, ASSIGNOR TO JOHN WOOD MANU- FACTURING COMPANY, OFCONSHOHOGKEN, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA LIQUID DISPENSING- APPARATUS Application filed January 24, 1931. Serial No. 511,031.

My invention relates to apparatus which may be advantageously employed in dispensing gasolene through a flexible hose having one end connected with a stationary pump stand and having its free end provided with a nozzle including a manually operafive valve controlling the dispensation of liquid therethrough, in conjunction with means at said nozzle whereby opening movement of the nozzle valve pulls a flexible connector extending along the hose to operate an electric switch in the pump stand to close the circuit of an electric motor adapted to then operate the pump to supply the liquid for discharge through the hose.

As hereinafter described, my invention includes the combination with a lever adapted to operate the nozzle valve, of a link pivotally connected to said lever and to said flexible connector, constructed and arranged so that when the lever is released by the operator to permit the nozzle valve to close and stop the dispensation of liquid therethrough, said link is shifted to relieve the connector of tensile stress; so that, in such idle position of said lever and link, the hose may be flexed to any desired position without stress upon said switch. Relative movement of the connector with respect to the hose, incident to fiexure of the latter to insert the nozzle in the receptacle to be supplied with liquid or to hang the nozzle and hose in idle position upon the pump stand, merely effects idle movement of said link without movement of said lever. However, when the hose and nozzle are thus arranged in dispensing position, movement of said lever to open the nozzle valve causes said link to tensilely stress the connector and thus effect the desired movement of said electric switch.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings, Fig. I is an elevation of an apparatus conveniently embodying my invention, with the hose and its nozzle released from said support.

.Fig. II is a fragmentary longitudinal sectional view of the nozzle and its appurtenances indicated in Fig. I.

Fig. III is a transverse sectional View of said nozzle and its appurtenances, taken on the line III, III in Fig. II.

In said figures; the pump stand includes the base 1, casing 2, platform 3, center frame 4, casing 5, and dome 6.

The liquid to be pumped is withdrawn from a subj acent tank through the pipe 8, the screen casing 9, and the pipe to the rotary pump 11 which has its casing rigidly connected with the lower side of said platform 3. The rotor 12 of said pump is provided with the pulley 13 adapted to be driven by the belt 14 extending around the pulley 15 on the armature shaft 16 of the electric motor 17.

Said pump 11 is adapted to discharge the liquid through the pipe 19, the meter 20, and the pipe 21 into the sight gage 22 from which it gravitates through the pipe 23 into the flexible dispensing hose 24. Said hose has. at

its free end, the nozzle 25 containing the valve 26 which is normally closed by the spring27 upon the port seat 28. Said valve has the stem 30 extending through the stuffing box 31 in the nozzle 25 adapted to be operated by contact with the boss 32 on the lever 33 which is fulcrumed at 35 in the nozzle frame 36.

Said lever 33 is normally stressed to the idle position shown in Fig. II by the spring 37 encircling said stem 30 and boss 32. The free end 39 of the lever 33 extends in the guide slot 40in said nozzle frame 36 which prevents lateral displacement of said lever and limits the movement thereof by said spring 37. The link 41 comprising a pair of opposite side plates is pivotally connected to said lever 33 by the pin 42 which is reduced at its opposite ends which are respectively riveted in said link plates. The opposite ends of said link plates 41 are connected by the pivot pin 43, which carries rollers 45 at its opposite ends respectively engaged in the guide recesses 46 in the parallel flanges 47 on said nozzle 25. Said pin 43 carries between said rollers 45 the spool 48 having the groove 49 intermediate of its length, holding the end bight 50 of the flexible connector 51, which projects from the clamp block 52 in which it is detachably secured by the screw 53.

[ill

It may be observed that when in the idle position shown in Fig. II, said lever 33 is in spaced relation with the stem of the valve 28, and that said link d1 and the means above described connecting it with said flexible connector 51 and adapted for reciprocation in the guide flanges L7, constitute plunger-like means with which the lever 33 and spring 37 cooperate to afford automatically compensated adjustment therefor in relation to the switch and valve, and permit flexure of the hose without movement of either the valve or the switch; the relative movement of the nozzle end of said flexible connector, incident to the flexure of the hose, being compensated by idle oscillatory movement oi said link and lever.

Said flexible connector 51 extends through the flexible tubular sheath wl ich extends along said hose Ed and is secured at its op posite ends between the ends of the clamp bands 55 by respective screws 56. Said connector 51 extends from said sheath 54 through the rigid elbow tube 57, which is supported by said pipe 23 and said connector extends around the pulley 58 and is tensilely stresset by the weight 59 suspended therefrom. Said pulley is operatively connected with the electric switch conveniently comprising the evacuated glass tube 60 within the switch casing 61 which is rigidly mounted in said pump stand casing 5 and controls the operation of said motor 17.

It is to be understood that the electrical control mechanism above described may be conveniently manipulated by the operator who extends his fingers through the space 63 between said lever 33 and said nozzle frame 36, with his thumb around the nozzle 25; so that after the operator has flexed the hose 9d in proper position to insert the nozzle tube S t in the receptacle to be charged with liquid; he may conveniently manually grip said lever 33 toward said nozzle 25 to open said valve 26 to permit the liquid to flow into the receptacle and contemporaneously pull said connector 51 to close said switch to start said motor 17 to actuate said pump 11 to continually dispense the liquid through said nozzle until the operator relaxes; his grip and permits the spring 27 to shut said valve 26 and the spring 37 to move said lever 33 to the idle position shown in Fig. II. 'lhereupon,

said nozzle may be hung iu idle position upon the support 66 projecting from said pump stand casing 5.

As indicated in Fi II, said support 66 may have flanges 6! :nd 68 extending respectively above and below it with. holes 69 and 70 therein adapted to receive a U- shaped lock member 71 so that when thus supported and locked, the nozzle tube G l projects within the casing 5 and the nozzle lever cannot be manipulated to either open the valve 26 or operate the pump 17. However,

I do not desire to limit myself to the precise details of construction, arrangement, or method of operation herein set forth, it is obvious that various modifications may be made therein without departing from the escombination with a stationary pump stand;

of a liquid dispensing pump in said stand; an electric motor operatively connected with said pump; an electric switch adapted to control the energizing circuit of said motor; a liquid discharge conduit in communication with said pump and including a flexible hose; a nozzle on said hose; and switch operating means extending from said nozzle to said switch, including a lever at said nozzle and a flexible connector extending from said nozzle to said switch, and a link pivot ally connecting said lever with said flexible connector, extending transversely to the latter, and constructed and arranged to oscillate on said lever and permit flexure of said hose and relative movement of said flexible connector and link, without movement of said switch, when said lever is in idle position.

2. Apparatus as in claim 1, including a valve in said nozzle, in cooperative relation with said lever; whereby said lever may be operated to contemporaneously open said valve and shift said switch to operate said pump, and said lever may be reversely operated to permit said valve to close and stop the operation of said pump, and said lever and link may be oscillated by flexure of the hose, without operation of said valve.

3. Apparatus as in claim 1; wherein the nozzle includes means adapted to guide the joint between said link and flexible connect or, in longitudinal movement of the latter.

4. Apparatus as in claim 1; wherein the nozzle includes means adapted to guide the joint between said link and flexible connector, in longitudinal movementof the latter, comprising a recess in the nozzle frame and a roller carried by said joint and arranged to traverse said recess.

Apparatus as in claim 1; wherein the nozzle includes means adapted to guide the joint between said lever and said link in oscillatory movement thereof.

6. Apparatus as in claim 1; wherein the nozzle includes means adapted to guide the joint between said lever and said link in oscillatory movement thereof, including a slot in the nozzle frame in which the free end of said lever is fitted to slide.

7 Apparatus as in claim 1, including a valve in said nozzle, mounted to reciprocate transversely to the axis of said hose, in cooperative relation with said lever; whereby said lever may be operated to contemporaneously move said valve and link transversely to the axis of said hose and move said flexible connector parallel with the axis of said hose, by said link.

8. In liquid dispensing apparatus; a nozzle structure including a valve adapted to control the dispensation of liquid therethrough; alever in cooperative relation with said valve; a link pivotally connected with said lever; and guide means for guiding the free end of the link longitudinally of the nozzle; whereby movement of said lever to operate said valve occasions movement of one end of said link transversely with respect to said nozzle, and the other end of said link longitudinally with respect to said nozzle; and means carried by the guided end of said link adapted for engagement with a flexible connector.

9. Apparatus as in claim 8, including means adapted to guide the joint between said lever and link in oscillatory movement thereof.

10. Apparatus as in claim 8, including a spring normally stressing said lever away from said valve, to idle position, and means limiting the movement of said lever by said spring.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvanian, this twentieth day of January, 1931.

CORNELIUS A. DESIMONE.
